3M™ fire barrier silicone sealant 2000+ is an elastomeric, 1-component, neutral-cure silicone sealant. This ready-to-use sealant cures upon exposure to atmospheric humidity and forms a flexible firestop seal for construction joints and through-penetrations in fire-rated assemblies. 3M™ fire barrier silicone sealant 2000+ is firestop tested up to 3 hr in accordance with ASTM E 814 (UL 1479) and CAN/ULC S115, as well as fire-resistance tested up to 4 hours for construction joint systems in accordance with ASTM E 1966 (UL 2079). We engineered this silicone sealant to provide +/-13% compression and extension capability. This flexible firestop sealant is re-enterable and repairable, exhibits exceptional adhesion and bonds to most common construction materials and provides excellent weatherability during construction.
